Account-wide Mounts, Pets, and Achievements

It’s finally here, and you’ll be able to enjoy just about every mount and pet you own on any character, and any license, under a single Battle.net account. You can also work on a wide variety of Achievements from multiple characters. Please be aware of the rules and guidelines we’ve just posted for how you can coalesce your account-wide pets and mounts smoothly and safely.

*To see all of your achievements, pets, and mounts, you’ll want to log into every character at least once.

So..for example, if I were to have 99 flag returns in WSG, and I got one more on my lvl10 alt, I would be awarded the 100 flag return achievement?

That seems really nice, actually.

Also, would this be included for the Loremaster (meta) achievement?

No. That achievement is a meta achievement to a larger overall achievement. Once one player gets all 100, then it will be for all characters, but multiple characters cannot contribute to the same meta.
